Agreed. Don’t get me wrong, I wouldn’t complain about 13.4 when it could have been 17.3, but too close for comfort.

Seems it’s trended the first wave stronger and the second weaker.

GFS seems to be onto the Euro’s idea of two rounds of snow, one earlier Monday and then a larger one Monday night/Tuesday morning. Hopefully it has the right idea with the strength of the second round! Looking ahead, the late week storm still seems to be trending east. Still mostly ice/rain on the GFS, but it’s coming into line with a more favorable path for us.

TWC appears to have lowered amounts for the first system but raised them for the second system, and is predicting all snow in the North Hills for both (12-24 total from both storms). Still lots of time to change.

NWS afternoon forecast discussion still not biting on a significant snow event Mon/Tues.

Euro looks a little better, 6” and some zr. And 4” of all snow on the late week system.

The GFS still looks beautiful, massive snowfall rates and dropping 8+ inches on us overnight Monday night.

If we get two back to back that big, we’ll be within striking distance of the record and will have no choice but to root for it. (But the GFS does seem to be hinting at a pattern shift toward the end of its run, but way too early to think about that.)

Interestingly, TWC is liking the later week storm for 6-12” over a 36+ hour period.

True. It was the most recent model to predict that magnitude of cold. On that note, both models put us close to 0 after the Mon/Tues storm and the Euro puts us close to 0 after the Thurs/Fri storm. Para brings subzero cold Wed. AM.

I can’t say I know what model has been superior, they’ve all struggled to get a handle on how this pattern will play out for really the entire month of February so far. I just remember there being a 50 degree swing from one run to the next on the Euro, going from a historic cold snap to temperatures well above freezing. But that was the first run that it picked up the 2/9 system, not several days after it had been painting the exact same picture as the GFS for a number of runs. The Euro did beat the GFS significantly in recognizing that the brutal cold would not reach our area and we would instead lie in that active storm track most of the month. And the GFS did try to give us that monster storm this coming Sunday for a run or two that no other model really bit on.

The Euro did do this with our 2/9 storm 5 or 6 days before, suggesting the system would track way west and pump our temps up close to 50. That didn’t verify.

But that’s the scary part. These models are ~4 days from the onset of precip and depicting completely different scenarios. Not just a little bit different, but completely out of phase with each other.

Euro is wet on Tuesday, GFS is wet on Thursday/Friday. What are the chances we get more rain than snow?

So there is validity to the “0z and 12z are better” argument?

So it’s probably just as valid. I only ask because I liked the 12z’s model of both storms next week better than the 6z and 18z.

So honest question: why do people view the 6z and 18z GFS as less valid than the 0z and 12z?

Ah, so the NWS doesn’t like this pattern for snowfall.

GFS gives it a similar track, though slightly earlier and with slightly higher temps.

If I were a betting man, I’d say the 2m temperature will not drop below 20 during this event, but that’s an entirely different topic.

Euro seems to be on about 8” of mostly snow, with about 6” in 6 hours between 6z and 12z Tues. Though it’s also mixing p-types with temps in the teens. I’ll bet my entire bank account that not one drop of rain or sleet will fall with an air temperature below 20.

The later week storm seems to be trending west and could destroy our snowpack no matter how much snow we get from the earlier system, especially if the Euro verifies.

Wouldn’t say I’m worried about that, it just speaks to the magnitude of the cold air. Subzero in Dallas has only happened four times in recorded history.

Subzero cold seems to possibly be in the cards for Dallas...

So the setup you’re seeing continues to leave cold air entrenched over our area for most precipitation that falls to be snow?
